BOBBIN-HOLDER.

Specification of Letters Patent.

Patented Nov. 22,1921.

Application filed December 17, 1920. Serial No. 431,457.

To all whom it may concern Be it known that I, ALBERT HENRY FLnon, acitizen of the United States. residing at Lakewood, in the county ofCuyahot'a and State of Ohio, have invented certain new and usefulImprovements in Bobbin-Holders, of which the following is aspeciiication.

My invention relates to improvements in bobbin holders or supports, thepresent embodimentof the invention being particularly designed andadapted for use in receiving and supporting. the conical shaped tubes orshells commonly known as cop-tubes carrying the cops of thread or yarnused in connection with various forms and types of knitting, sewing andlooping machines.

The primary object of the invention to provide a generally improvedholder or support of this class, which will be exceedingly simple inconstruction. cheap of manufacture and etiicient in use.

A further and very important object is the provision of an improvedsupport adapt-- ed to be readily attached to or detached from theordinary base plate and spindle used in connection with knittingmachines. and when so mounted and attached adapted to receive the partsand interlock with the base portion of the coptube whereby the latterwill be securely supported and retained as the thread or yarn is takenfrom the top of the cop and cop-tube.

lVith the above mentioned and other ends in view, the invention consistsin the novel construction, arrangement and combination of parts.hereinafter described, illustrated in one of its embodiments in theaccoinpan v ing drawings. and particularly pointed out in the appendedclaims.

Referring to the drawings, forming a part of this specification. Figure1 is a view partly in side elevation and partly in section of a holderor support applied to an ordinary cop-tube and to t 1e conventional formof cop-tube support or base plate and spindle.

Fig. 2, a cross sectional view of the same taken on line 22 of Fig. 1.

Fig. 3, a perspective view of the improved spindle receiving andclamping screw for attaching the support to the ordinary cop-tubereceiving spindle.

Similar numerals of reference designate like parts throughout all thefigures of the drawings.

The improved holder or support is adapted to be used in connection withany suitable and convenient bobbin or tube spindle 1]., and supportingbase 2, and arm or supporting rod 3. 1n the present instance, thecop-tube receiving spindle l. and supporting base 2, and arm 3, are ofthe conventional form frequently used in connection with knittingmachines.

In adapting the device for use in connection with the conventional formsor devices above referred to, and particularly in con nection with theconventional form of coptube l-. usually made of compressed paper orsuitable composition, the support 5, is preferably of truncated coneshape spun up from suitable metal forming the inclined side walls andterminating at its top in a supporting head 5, the latter being providedwith a central opening formed by struck out portions providing anannular flange 5 The opening formed by the struck out flange 5", isadapted to receive the top portion of the spindle l, and as a means ofsecurely fastening the support 5.upon the spindlc'l, the interiorportion of the opening or flange 5 is provided with threads adapted toreceive a spindle receiving and clamping device consisting, in thepresent instance, of a sleeve screw 6, embodying the angular shaped headand provided with exteriorly threaded tongues 6 the latter beingpreferably tapered on their outer sides, as shown most clearly in Fig. 3of the drawings, whereby upon drawing the same downwardly or from leftto right in the threaded opening and about the spindle 1., the latterwill become lirmly clamped to securely support the coptube holder 5,upon the spindle 1.

As a convenient means of removably attaching the cop-tube 4;, upon ordetaching the same from the inverted cup shaped support when the latteris attached to the spindle 1, as above referred to, the inclined sidesof the support 5, are preferably provided with corrugations 5. arrangedin spiral or thread form, said corrugations being preferably formed outof the side walls of the support. as shown. whereby to securely receive.and interlock of the base portion of the cop-tube. as shown most clearlyin Fig. l of the drawings.

By virtue of the construction of the holder or support 5. as abovedescribed, it will be obvious that the surfaces of irregularly madecones or cop-tubes l, will. assume a perfectly with the inner surfacesconical shape when threaded or seated upon the support through themedium of the corrugated threads 5.

Having thus described one of the embodiments of my invention, withouthaving attempted to set forth all the forms in which it may be made, orall the modes of its use, what I claim and desire to secure by LettersPatent, is,

1. In a cop-tube support, a conical-shaped cop-tube support shaped toreceive and engage within the base portion or the cop-tube and providedwith threaded cop-tube engaging corrugations and terminating at 1ts topin a tapered threaded opening provided with a tapered clamping screw toreceive and clamp the cop-tube spindle.

2. In a cop-tube support, a truncated coneshaped cop-tube support toreceive the base portion of a cop-tube and provided with threadedcorrugations, said support terminating at its top in an attaching headhaving a threaded opening, and a split cla1np ing screw in said threadedopening to receive and clamp a cop-tube spindle.

3. In a cop-tube support, a supporting ar1n,a supporting base thereon, aspindle on said base, a threaded cone-shaped support provided with asupporting head having a threaded opening surrounding said spindle, anda sleeve clamping screw surrounding said spindle in said threadedopening in cooperative relation to said threaded coptube support.

4. In a cop-tube support, a main supporting arm terminating in asupporting dish, a central spindle on the latter extending upwardlytherefrom, a threaded tubular support provided at its top with asupporting head having a central threaded opening, and a sleeve clampingscrew receiving said central spindle and provided with threaded clampingtongues arranged in said threaded opening of said supporting head andsurrounding and clamping said spindle in cooperative relation to saidthreaded cop-tube support. r

In testimony whereof I have aflixed my signature.

ALBERT HENRY FLECK.
